Our experiments began on day one by filling a 400ml beaker with ice and an arbitrary amount of rock salt in order for our…
Keep a small amount of the solid to determine its melting point. This is so we can use the melting point in our results afterwards. Make sure there is enough solid left in case the melting procedure goes wrong.…
* You could perform a sulfate test to determine the percentage of sulfate that was present. You could also determine the percentage of aluminum or potassium in the crystals.…
In this Lab there were four different stations to experiment with, my partner and I started with grabbing our goggles, and then we started with station 4, solubility, we had add a small amount of 4 different liquids (Hexane, Ethanol, Water, or Vegetable oil) to a well, then we had add a solid (Salt,Sugar, or Lard) to each of the 4…
Each substance was observed inside their containers and the hypotheses were based on these observations. The volumes of each substance was then measured inside their containers. Each substance was then weighed and density calculated. After, each substance was observed under magnifying glass, smelled and touched to determine texture. Lastly, each substance was tested for solubility.…
2) First, do steps (3-6)to find out the properties of salt, sugar, dirt, and baking powder.…
The purpose of this experiment was to separate the component of three mixtures sand, sodium chloride and calcium carbonate then calculate the percentage by mass of each component recovered from the mixture. The other purpose of this experiment was to show us the students the concepts associated with physical and chemical properties of substances.…
Complete this week’s lab by filling in your responses to the questions from the Geoscience Laboratory. Select answers are provided for you in red font to assist you with your lab work. Although you are only required to respond to the questions in this worksheet, you are encouraged to answer others from the text on your own.…
We had to shake sugar cubes in a jar for 3 minutes, because we are talking about Mechanical Weathering. The purpose of this lab was to see what happens to rocks during Mechanical Weathering. The sugarcubes represented the rocks during Mechanical Weathering. We used sugarcubes because the Sugarcubes were the only thing close to rocks that will break up. In the first test ,we thought that the sugar cubes would break up. In the Second test we thought the Sugar cubes would break up more than the first time. By the 3rd time we knew that the Sugar cubes would break up completely. What happened the first time was the cubes broke up. The 2nd time the cubes Broke up more. The 3rd time the cubes broke up, but not completely. Our data does not make a…
They need to use the same rocks from the backyard. You can’t compare different types of rocks. Just because it appears to shrink doesn’t mean it actually did. You need real data of what the mass of the rocks were before the rainstorm.…

A sugar cube is a carbohydrate made of moistened sugar. For something to be a living thing, it has to have cellular organization, contain similar chemicals, and have the abilities to reproduce, evolve, use energy, grow, and respond. A sugar cube has several of these characteristics, raising the question of whether it is living or not.…
Chemical Weathering is the process of disintegration or decomposition of rocks due to chemical processes. It alters the intrinsic properties such as chemical structure, composition and density of the minerals that the rock is made up of.…
The size distribution is often of critical importance to the way the material performs in use. A sieve analysis can be performed on any type of non-organic or organic granular materials including sands, crushed rock, clays, granite, feldspars, coal, soil, a wide range of manufactured powders, grain and seeds, down to a minimum size depending on the exact method. Being such a simple technique of particle sizing, it is probably the most common.…
Weathering is a major process which has helped shape the landforms of New Zealand. Weathering is a process of rock being constantly worn away and broken down by the weather or the actions of plants and animals. Weathering is divided into two major groups: Chemical weathering and Physical weathering. Chemical weathering happens when chemicals, such as acid in rain water, gradually dissolve and eat away at rocks. For example, limestone rock dissolved by rain water is responsible for many caves and gorges in New Zealand, including the Waitomo caves. The picture on the right is a picture of a cave in the Castle Hill basin, Canterbury, which has been formed by rain water dissolving limestone. This causes the limestone to wear away and create a new shape. Physical weathering makes rocks break apart in sheets, blocks or grains. It can further be divided into three categories: Exfoliation, Freeze-thaw action and biological weathering. Exfoliation is when Rocks which are warmed by the sun expand and shrink as they cool at night. The outer layer of the rock expands more, because it is directly exposed to the suns heat, and soon it separates from the rock and peels off. Freeze-thaw action is when water seeps into cracks in a rock and then freezes and expands. As the temperature…
